Darvin Adams, Auburn

Adams nabbed All-SEC honors in 2010, and compiled 115 receptions for 1,978 yards and 17 touchdowns during his college years.

However, Adams needs to add some serious bulk to his frame. He's as exciting as they come in the open field, but facing more contested NFL coverages could become a major issue for Darvin unless he can prove his ability at the line of scrimmage.

At 6'3", 185 pounds, the best thing he can do in the combine is prove his strength.

Jonathan Baldwin, Pittsburgh

Pittsburgh's Jonathan Baldwin kind of fell off the map in 2010, going from a top receiver to a questionable prospect.

He caught 53 passes for 822 yards and five touchdowns in his final season, but he's not the most eye-catching NFL prospect, especially at receiver, considering his 230 pound frame.

The main reason why is his apparent lack of agility. Baldwin has made plenty of circus catches in his career, but he made his living catching jump balls. He has to prove his ability to run solid routes in an NFL offense.
